A reliable source for Machine Vision Systems information and leading Machine Vision Systems Companies & Manufacturers.
Machine vision systems can be defined as some kind of technology that enables the inspection, evaluation, and identification of still, or moving, images by a computing device. This technology relies on a variety of methods which can be used for different applications ranging from identifying item defects, barcode reading, and product sortation to product checking, end-of-line vehicle inspection, and robotic production.

Machine Vision SystemsMachine vision is a technical system designed to mimic human vision. In industrial settings, machine vision refers to the computer "vision" used to control automated manufacturing equipment. Although machine vision systems differ by product, four key elements remain the same: a digital camera, sensor, computer and special image processing software.

The different types of machine vision systems include:
1D Vision Systems
These systems analyze the digital signal one line at a time rather than looking at a complete picture. These systems work by looking for any variance between the lines that were previously acquired and the lines that are subsequently acquired. 1D machine vision systems have the main function of detecting and classifying defects in materials that are manufactured in a continuous process like plastics, paper, metals, and many non-woven items.
2D Vision Systems
Two Dimensional vision systems provide area scans that work well for discrete parts. They are very compatible with many software packages. They are also the default technology that is used in many machine vision applications. They are found in continually-expanding resolution ranges.
3D Vision Systems
There are many different types of 3D machine vision systems. Stereo systems are used for capturing three dimension information by the use of two cameras that are horizontally displaced from one another. Each camera will provide an object image that is slightly different in projection from the others. The matching of points in one image with the same set of points in the second image is then possible. This task is called the correspondence problem.
Applications of Machine Vision Systems
Below is a list of some possible machine vision system applications:
Recognition and verification of optical character
Automated vision testing as well as measurement
Benefits of Machine Vision Systems
The benefits of machine vision systems include:
Machine vision systems improve manufacturing speed and reduce the amount of labor needed for operating the equipment. Machine vision systems also reduce scrap rates so there is a reduction of wasted materials.
Elimination of Human Errors
Since the human eye is not infallible, machine vision systems help in ‘qualitative interpretation’ by reducing human subjectivity during production processes. For the inspection of object details that are too small for discernment by the human eye, machine vision systems can be paired with high-resolution cameras. These vision systems can further eliminate operator fatigue as well as variances between different operators.
Machine vision systems are capable of measuring product quantities because of their accuracy, speed, and repeatability. For illustration, machine vision systems can be implemented on production lines and are capable of inspecting hundreds of parts per minute.
Machine vision systems safeguard against parts damage by removing the physical contact between a test system and the manufactured parts. They also reduce the time and fees required for fixing mechanical components as wear and tear take their toll. Machine vision systems help increase productivity further by increasing operation times, since machines will require less attention. This means that production deadlines can be met with ease and consistency.
Reduced downtime will inherently lead to increased productivity. But machine vision systems will take this concept even further. A machine vision system is capable of delivering corrective commands roughly with a speed that is one second faster than even trained operators can. This helps with the reduction of the need for manual correction of a system. It also helps with the stabilization of productivity levels.
Print Defects Identified
The identification of printing anomalies like incorrect color shades, missing letters, or blemished prints can be difficult. But, with a machine vision system, this task is easily handled.
There is a lower risk of employees suffering injuries when operating bulky, powerful machines since machine vision systems reduce both employee exposure to dangerous equipment and employee fatigue experienced while performing repetitive, mundane tasks. Since there is a reduction of human involvement in manufacturing with machine vision systems, they create safer working environments.
Product Flaw Detection
Machine vision systems are capable of detecting product abnormalities such as surface dents and scratches. If detection boundaries are carefully applied, acceptable flaws can be distinguished from unacceptable flaws.
More Accurate Measurement
The application of machine vision systems also involves the accurate determination of objects’ dimensions. Vision systems can locate and measure certain points on an image quicker and more accurately than people. These points include the radius, diameter, depth, and distance.
Machine vision systems are most commonly used for locating objects in applications like robotic guidance. For example, a machine vision system may be employed to find the location of coordinates for a particular object’s position. This information will then be used for picking up the object or performing another process that is location-dependent. Machine vision systems are multifunctional and can be applied in many different ways during manufacturing processes.
